Unable to connect to internet from aix server

I am unable to connect to internet from aix server. Already network interface en0 has been configured to network.
What is the procedure to connect the aix server to internet. I'm unable to ping or ftp to ibm website to download TL
Already the ftp,telnet daemon is active. I'm able to telnet/ftp to my local windows machine.
# ftp delivery04-bld.dhe.ibm.com
ftp: Unknown host delivery04-bld.dhe.ibm.com
How to proceed....

You don't need the daemons (ftp, telnet etc..) to be active on the AIX server, perhaps there must be a network restriction (firewall) which is preventing you to connect to the internet, en0 configured doesn't mean you can connect to the internet, time to revisit some basics and talk to the network chaps.
